We offer PC-mount transformers in a number of configurations to meet both the power and dimension requirements of your electronics projects. In addition to the iron-core, through-hole transformers described on this page, we also manufacture surface-mount transformers in an array of configurations.
LPC-STYLE TRANSFORMERS
Low-profile PCB-mount transformers (LPCs) are designed to take up minimal vertical space. These types of transformers can be used for nearly any printed circuit board configuration where a slim overhead design is required. The semi-toroidal construction helps reduce hum as well as radiated magnetic fields.

ENCLOSED-WINDINGS TRANSFORMERS (International Standards)
These PC-mount transformers meet international isolation standards. They utilize an E-I laminate core and offer an effective alternative to LPC-style transformers when greater output power is needed and vertical space is not quite as limiting.
Sun Transformer can design and manufacture PC-mount transformers to meet nearly any requirement. For more information about how we can provide your transformer needs, please send us your specifications or call us today!
All Sun Transformer products are available lead-free and RoHS compliant upon request.
